This package includes a fix for HMC Version 8 Release 8.2.0.  You can reference this package by APAR MB03871 and PTF  MH01486. This image must be installed on top of HMC Version 8 Release 8.2.0  with mandatory PTF MH01454.

Enhancements

• This PTF disables SSLv3 on the HMC user interfaces.   After applying this PTF, remote access to the HMC (Browser, ASM, GUI vterm, and pegasus) will require clients  that support TLSv1.0 IBM i secure remote 5250 console will require TLSv1.1 or higher.  The PTF also disables all ciphers except TLSv1.2 on HMC/FSP connections where the server firmware level supports it.
  
  
• Enhanced the chpwrmgmt and lspwrmgmt commands to support a new power saver mode of fixed_max_frequency . 
  
  
• For HMCs set to security mode  nist_sp800_131a, this PTF changes the HMC-Server FSP encryption mode to enforce TLS1.2.  This implies that all POWER6 and POWER7 servers must be upgraded to a firmware level that supports TLS1.2 prior to apply of this PTF when using nist_sp800_131a security mode.

Notes:

1. The Install Corrective Service task now allows you to install corrective service updates from the ISO image files of these updates. You can download these ISO image files for the HMC, and then use the ISO image file to install the corrective service update. You no longer need to burn CD-R or DVD-R media to use the ISO image file to install corrective service.
2. This image requires DVD -R media.
3. To install updates over the network, select the *.iso file on the "Select Service Package" panel of the Install Corrective Service task. The HMC application extracts the files needed to install the corrective service. If you are using USB flash media, copy the *.iso file to the flash media, and then select the file when prompted.
4. The updhmc command line command has also been modified to use the *.iso file. To use the command, follow the syntax in this example:
   updhmc -t s -h <myservername> -f </home/updates/corrrective_service.iso> -u <HMC_username> -i

In all cases, the HMC application extracts the files needed to install the corrective service.
